Bug#638504: ITP: mat -- Metadata anonymising toolkit

[intrigeri <intrigeri@debian.org>]

Update: I've been maintaining a Debian packaging [0] of the MAT for
testing purposes, and also because we've been shipping it into
Tails [1] for a few months.

I have been waiting for the dust to settle down, for bug reports
flowing from brave early adopters to arrive and be dealt with. I think
the program will soon be mature enough to be worth uploading into the
Debian archive. Stay tuned.

In the meantime, upstream have gotten themselves a website [2].
